A lockdown at South Lakes High School, Terraset Elementary School and Langston Hughes Middle School around 12:40 p.m.was lifted earlier today, according to a Fairfax County Public Schools spokeswoman.

Local police receive a report that a student with a gun was at South Lakes High School this afternoon. Police said the report was false and lifted the lockdown around 1:13 p.m.

School officials said the situation was resolved in a peaceful and quick manner.

Hughes Middle School’s lockdown, which went into effect around 1 p.m., was lifted at 1:12 p.m. All classes resumed as normal by 1:25 p.m., according to the school’s principal, Aimee Monticchio.

“Staff and students did a great job responding to a very delicate situation,” Monticchio said.

Some parents said the school system did not inform parents and guardians of the lockdown quickly enough.

Parents at South Lakes High School, where the lockdown occurred for 27 minutes, received an email about the three lockdowns at 1:21 p.m.
